A controversial Norcross drug treatment facility with ties to the Church of Scientology will avoid any potential criminal charges after surrendering its license to the state.

But the investigation into allegations of insurance fraud by those running the facility isn't over, Gwinnett County District Attorney Danny Porter said.

"Narconon as a corporate entity has been relieved of criminal liability but no individual is," Porter said Wednesday. "Certainly we've discovered discrepancies between what was billed and what was provided. The key now is to identify those individuals who were submitting the claims."
